If you don't have Legacy USB mouse support in your BIOS, you'd have to send
the mobo maker a request to add support for the various C2xxh Int 15h
functions for USB mouse (which is an emulated mode to interface with the HID
device, they already do it for the KB so just need to add for the mouse).

Thanks, that is what I suspect. Hopefully someone with this Motherboard and
a USB mouse that is working will have some info. I have updated my BIOS.

Should prove most interesting which one has the fix for USB mouse support.
